Playing Card Symbols

Hi all,

I just ordered my first Arduino, and have started playing with it a little bit. I am planning on hooking up a few LCD screens to it and programming it to allow a few players to play a card game. I have seen screen shots of people with the diamond, spade, heart and club symbols on their LCD screens, and I was wondering if someone could tell me how they did it, and if there is a specific LCD screen you recommend? I am thinking of a large 20x4 screen, to maximize display options.

Oh, one more question. Is there a certain type of LCD screen that is best for viewing outside? Certain back-lit colors or anything like that?

Thank you,

These symbols are in the character generator rom of the display. see your display data sheet to see if your display has them. They are usually numbers above 128 you just write to the display in place of the ASCII ones.
Most LCDs are fairly useless outside, you need a strong back light.

My favourite playing card joke is:-

If it's a HD44780 display then you can always create some custom characters if it doesn't have them.
